IIMPRO'VED SCHOL-DESK.

To all to'whofm, it ma/y concern:

Be it known that we, Ems'r W. GILLES and J U'LEs lowing is a full and exact description thereof, reference being had to the accompanying drawing, and to the letters of reference marked thereon. l

The nature of our invention consists in providing a hinge, adapted to a shoulder, occupying but little space, made easily adjustable by the hand, so that theteacher,

pupil, or any person, can easily and readily let down table can be let down perpendicular, and when raised,

the table-leaf and raise and fasten the same again.

This table-leaf, or top part of the desk, is so constructed, by means of this hinge, as to drop, and be .raised horizontally, being held by part A, which is an arm of cast-iron, to which the table is made fast and secure, and this arm is represented on the diagram in Figure 1.

` This arm is connected with an upright of iron, and at a short distance from its upper extremity, it is made Y fast by a pivot or bolt, and is held by part B, which is representedon the drawing in Figure 3, corresponding to the representation in Figure 2, which presents the side view.

By our improvement, we can, without difficulty o'r delay, place the table andthe seat perpendicular, either together or Separately, as may be desirable.

Attached to the cast-iron arm A, in fig. 1, and made apart of it, is the upper part of the hinge-which is held to the upright casting, at B, on fig. 1, bya pivot, movable at pleasure.

Connected with this arm, and made into a hinge by the use of a pivot, is a circular-slotted link, lettered O, f

made so as to pass freely and easily over another pivot, D, at its lower extremity, where there is a shoulder, on which it rests when the table is up, holding it firm and fast.

By raising the table slightly, and displacing from the pivot D the lower end of this circular-slotted link, the

it fastens itself.

What we claim as our invention, and desire to secure by Letters Patent, is-

The combination of the arm A with slotted link C and standard B and its connections, by means of which the table is let down perpendicular, and whenraised up, is held fast and secure, substantially as specified.
